std::basic_string_view::remove_suffix \- std::basic_string_view::remove_suffix

.SH Synopsis
   constexpr void remove_suffix( size_type n );  \fI(since C++17)\fP

   Moves the end of the view back by n characters.

   The behavior is undefined if n > size().

.SH Parameters

   n - number of characters to remove from the end of the view

.SH Return value

   \fI(none)\fP

.SH Complexity

   Constant.

.SH Example


// Run this code

 #include <iostream>
 #include <string_view>

 int main()
 {
     char arr[] = {'a', 'b', 'c', 'd', '\\0', '\\0', '\\0'};
     std::string_view v(arr, sizeof arr);
     auto trim_pos = v.find('\\0');
     if (trim_pos != v.npos)
         v.remove_suffix(v.size() - trim_pos);
     std::cout << "Array: '" << arr << "', size=" << sizeof arr << '\\n'
               << "View : '" << v << "', size=" << v.size() << '\\n';
 }

.SH Output:

 Array: 'abcd', size=7
 View : 'abcd', size=4
